## Gabber

Gabber provides the plumbing for realtime, multimodal AI applications. Instead of stitching together separate speech recognition, speech synthesis, and vision services, teams use Gabber's orchestration engine to wire them into a single low-latency pipeline. The platform's App Flow Builder is a visual canvas where developers drag composable nodes for inference, logic, and state, then connect them into an application that can see, hear, and respond in under a second.

The system is built around streaming and multi-participant scenarios. Apps can mix video, screen, audio, and text inputs from multiple streams and users at once, making it suited to live coaching, interactive avatars, gaming companions, and assistive tools. Developers bring their own models or use Gabber-hosted options, and custom building blocks let apps call external APIs and SDKs so the AI can take real actions.

Deployment is flexible: teams can run on Gabber's managed cloud or host the stack locally. Pricing is pay-as-you-go per session hour, and concurrent sessions are unlimited, which keeps the cost model predictable for prototypes and production apps alike.

**Pricing & Plans:** Pay-as-you-go per session hour (around $0.50/hour base session plus STT at roughly $0.15/hour; TTS and LLMs priced at cost or by provider). Enterprise plans offer custom integrations, dedicated infrastructure, volume discounts, and priority support. A free tier/get-started path is also offered.

- **Graph-based orchestration:** A drag-and-drop App Flow Builder connects inference, logic, and state nodes so you can design complex realtime flows without custom glue code.
- **Multimodal realtime inference:** Built-in low-latency orchestration for vision-language models, speech-to-text, and text-to-speech in a single pipeline.
- **Multi-stream, multi-participant:** Combine video, screen, audio, and text from several streams and participants simultaneously for rich interactive apps.
- **Composable, extensible nodes:** Mix and match building blocks, or write custom nodes to interface with your own API or SDK so the AI can act on external systems.
- **Flexible deployment:** Run in Gabber's managed cloud or host the stack locally, with unlimited concurrent sessions and per-hour billing.

**Strengths:** Low-latency orchestration engineered specifically for realtime multimodal apps; Visual builder lowers the barrier to wiring STT, TTS, VLMs, and LLMs together; Unlimited concurrent sessions with transparent per-hour pricing; Custom nodes and integrations let the AI take real actions

**Limitations:** Pay-as-you-go hours can add up for always-on production workloads; Realtime multimodal work still requires developer skill and testing; Some advanced app templates and features are gated behind higher tiers

## Gradium

Gradium targets teams building conversational voice agents, telephony bots, and real-time translation experiences where latency decides whether a product feels natural. Its model lineup covers the full loop: text-to-speech for synthesis, speech-to-text for transcription, live voice-to-voice translation, instant cloning from a short audio sample, pro cloning for production-grade custom voices, and voice design that creates a brand-new voice from a text description alone.

The platform is API-first, with SDKs for Python and Rust, WebSocket streaming, semantic voice activity detection, custom vocabularies, code-switching support, and integrations such as LiveKit and Pipecat so teams can drop it into existing agent stacks. Gradium also ships Phonon, an open on-device TTS model that can run offline, which matters for privacy-sensitive or embedded deployments.

Pricing is credit-based across five self-serve tiers plus enterprise. Credits map to usage: text-to-speech costs 1 credit per character, speech-to-text 3 credits per second, speech-to-text translation 4 credits per second, and speech-to-speech translation 30 credits per second. Higher tiers unlock commercial use, more custom voices, pro clones, and better concurrency, while enterprise adds dedicated inference, on-premises deployment, and options such as Baseten or SageMaker endpoints.

**Pricing & Plans:** Free tier with 45k credits per month. Paid plans run $12/mo (XS), $39/mo (S), $312/mo (M), and $1,480/mo (L) on monthly billing, with yearly billing giving one month free. Usage is credit-based (1 credit per TTS character, 3 credits per STT second, 30 credits per second for speech-to-speech translation). Enterprise pricing is custom.

- **Ultra-low-latency voice models:** Text-to-speech, speech-to-text, and live speech-to-speech translation reach roughly 50 ms to first audio, tuned for conversational agents rather than batch processing.
- **Tiered voice cloning and voice design:** Clone a voice from a short sample for everyday use, move up to pro cloning for production quality, or generate a brand-new voice from a text description.
- **Developer-first API and SDKs:** WebSocket streaming, Python and Rust SDKs, custom vocabulary, semantic VAD, and code-switching support make integration straightforward for agent builders.
- **Open on-device TTS with Phonon:** Phonon is Gradium's openly available TTS model that runs on-device for offline or privacy-sensitive deployments.
- **Scaling and deployment options:** Gradium handles concurrency tiers for growing traffic and supports dedicated inference, on-premises deployment, and Baseten or SageMaker endpoint hosting.

**Strengths:** Very low latency tuned specifically for live voice agents rather than offline batch jobs; Full voice stack in one API: TTS, STT, translation, cloning, and voice design; Genuine free tier (45k credits/month) and low $12/mo entry point for prototyping; Enterprise-grade options including on-premises deployment, data residency, and an open on-device TTS model

**Limitations:** Credit-based pricing is harder to forecast than flat per-seat plans, and unused plan credits expire monthly; Pro voice cloning and higher concurrency sit behind the larger monthly tiers; Feature depth varies by plan, so commercial use requires at least the XS tier
